Arron/m5 deliver therefrom obliquely against an elastic-fluid turbine-wheel, such passage being enlarged at the outer or longer side at A, and having an enlarged delivery chamber or passage (l for connection to a source of supply, and provided with a valve-seat N; a valve B with a flange W arranged to seat on the valve-seat N, and provided with a wedgeshaped extension B loosely litting in the rectangular nozzle-passage and being` eut away at B opposite the enlargement A in the eas ing; means tor adjusting said valve; a lip extension L on the outside ol' the nozzle-casing, arranged to extend in proximity to the tace of the turbinc\\'lieel, coacting substantially as described and l'or the purpose speeilied.

3. In a nozzle structure for elastic-lluid turbines, the combination ol a nozzle-easing A with the nozzle-oassage A rectangular' in Cross-section with parallel walls, arranged to deliver therefrom obliflucly against an elastic-lluid turbine-wheel, such passage being enlarged at the outer or longer side at A and having an enlarged delivery chamber or passage (l for connection to a source olE supply, and provided with a valve-seat N; a valve B with a flange W' arranged to seat o n the valveseat N, and provided with a wedge-shaped extension B loosely fitting in the vrectangulainoZzle-passage and being cut away at l opposite the enlargement r in the casing, said valve having astem screw-threaded internally; a stern G screw-threadcd at its inner endwithin the hollow valve-stein and provided with a collar G; a gland E embracing the stern G, with aisuitable packing material il beneath the same; a washer l between the packing material and the collar tl', a bandwheel il tor controlling the stem G; enacting substantially as described and lor the purpose specified.

in a nozzile structure tor elastic-fluid turbines, the combination oll a nozzle-casing A with the nozzlc-pasiaige A rectangular in "cross-section with parallel walls, arranged to deliver therefrom oblioucly against an elastic-fluid turbine-wheel, such passage being enlarged at the outer or longer sido at A and having an enlarged delivery chamber or passage C For conncrtion to a source of sn iply, and provided with a valve-seat N; a vaive B with a flange W arranged to seat on the valve- Seat N, and provided with a wedge-shaped extension B loosely litting in the rectangular nozzle-passage and being cut away at B opposite. the enlargement A in the casing; and means for adjusting said valve7 enacting substantially as described and for the purposeI specified.

5. In a nozzle structure tor elastic-fluid turbines, the combination of a nozzle-casing, having a nozzle-passage rectangular in crosssectionpwith the walls thereol" parallel, arranged to deliver obliduely against an elasticluid turbine-wheel, and having the outer side enlarged and with a delivery chamber or i passage connecting thereto: a valve, seated Within the casing, provided with a wedgeshapcd extension, the point ol the wedge ex tending in the direction ol the nozzle and interseeting the same, the outer rear portion ol" the wedge being cut away to correspond with the enlargement ol the passage; means ior adjusting the valve to regulate and control the flow ol the elastic lluid, tor the purpose speeilied.

t3. l'n a nozzle structure for elastic-fluid turbines, the combination of a nozzle-casing, having a iirizzltspiissilge rectangular in crosssection, with the walls thereol parallel, arranged to deliver obliquely against an elasticlluid turbineswheel; a valve, seated within the easing, provided with a wedge-shaped extension, the point ot the wedge extending in the direction ol" the nozzle and intersecting the same; and means for ad'usting the valve to regulate and toutrol the llow of the elastic ,lluid, for the pur )ose specilicd.

7. ln a nozzle lor elastic-lluid turbines, the combination oll a nozzle-casing with a nozzleassage with parallel walls, arranged to deliver obli( uely against r elastic-fluid turbine-whecll, and having the outer side cnlarged and connecting with a delivery chamber or passage, a wedge-shaped dividing part with the point ol' the wedge extending in the direction ol` the nozzle and intersecting the same, the outer rear portion ol' the wedfe being cut away to correspond with the enlargement ol' the nozzle-passage, coacting for the purpose spcciiied.

tt. ln a nozzle structure tor elastic-lluid l turbines, the combination oll a nozzle-casing, with a nozzle-passage rectangular in crosssection with parallel walls, arranged to deliver obliquel)r againstA an elastic-fluid turbine-wheel; a wcdge-shaped dividing part ranged within thepassage and dividing the same and arranged to permit the elastic lluid to expand toward the. center and be discharged l'rom said passage in substantially parallel lines, 'lior the purpose specilied.`
